i Specification of Letters Patent.

Patented Nov. 21, i916.

To all whom it may concern:

Be it known that I, EVAN MORGAN, a citizen of the United States, residing at Loon Lake, in the county of Stevens and State of Washington, have invented new and useful Improvements in Boat-Motor Supports, of which the following is a specification.

The object of this invention is to provide an improved form of motor support for boats of the lighter character such as row boats and canoes, and the invention is espe cially adapted for use on boats wherein the motors are detachably connected thereto in contra-distinction to that class of boats wherein the motor is initially or permanently attached.

Motor boat manufacturers now encounter considerable difficulty in selling boat motors to resort and other liverymen because of the fact that these light boats are soon racked to pieces when long subjected to vibration and propulsive thrust of the motor, the reason being that the average boat is not built to sustain any such stress in addition to the load normally imposed thereon. One of the principal reasons why a motor racks a row boat is because the motor is in most cases either attached directly to the tran som or to some portion of the hull at the stern of the boat, and in the one case motor vibration and propulsive stress is localized on the transom in such a manner as to loosen the juncture of the latter with the planking, while in the other case these thrusts are im posed directly upon the hull which is neither designed or capable of withstanding such stresses. It is because of the fact that the motor acts unequally on the hull and frame of the boat that the one is loosened with respect to the other and therefore it has been found. that stiffening means applied either to the hull or to the frame is incapable of correcting the defect.

Now it is one of the objects of my invention to entirely relieve hull portions of the boat from motor strain and impose all of the latter" not only upon the frame, but to impose this strain on the frame in such a manner that it will act and be directed longitudinally thereof. Therefore, in one embodiment of my invention I extend frame portions of the boat rearwardly beyond the stern or transom thereof and I attach to these rigid extending portions the motor with which the boat is propelled thereby die recting all of the strain on the frame, which is most capable of sustaining the same.

My invention includes the novel feature of extending the gunwales and keel portions rearwardly of the stern, and bracing such portions against each other to take up compression and tension strains, and attaching the motor to these rearwardly extending and rigidly braced portions. Therefore it will be seen that my invention is clearly distinguished from those types of motor supports which are pivoted to the boat.

My invention has other objects and features which will be more fully described in connection with the accompanying draw ings and which will be more particularly pointed out in and by the appended claims.

In the drawings, Figure 1 is a view in side elevation of the stern end of a row boat showing the same eouipned with the device of my invention. Fig. 2 is a plan view thereof. Fig 3 is a rear end elevation thereof with the motor omitted. Fig. 4 is a view in side elevation of a double ended boat showing a modification of my invention. Fig. 5 is a plan view thereof. Fig. 6 is a view in end elevation on a somewhat enlarged scale.

Like characters of reference designate similar parts throughout the different fig ures of the drawings.

As illustrated, and referring more particularly to Figs. 1 to 3, l designates the hull of a row boat which is usually formed of vertically edged or lapped planking, extending longitudinally of the boat from prow to stern thereof. A keel is indicated at 2 and the top margins of the hull are capped by inner and outer gunwales 3 and 4 which are usually spaced apart from each other but suitably connected, and also attached to the transversely disposed frame members 5. The rear seat 6 is disposed in a butting relationto the transom 7 and the latter is suitably attached to the planking 1, in any desired manner in accordance with the preferred type of manufacture. Rear oar-locks 8 are shown suitably mounted in blocks 9 which are secured to the gunwales in a rigid manner so that provision is made for rowing the boat when a motor is not employed.

Now referring to those portions of the structure constituting my invention, 10 designates an extension of the keel which projects rearwardly from the transom and which constitutes a rearwardly projectlng frame portion. The inner and outer gunwales 3 and i also extend rearwardly beyond the transom as indicated at 11, to form rigid rearwardly extending frame portions. A motor supporting board 12, or like element, is interposed between the gunwales and is suitably secured at its ends thereto, at 13, in any desirable manner, the said board being of sufficient depth, or in other words, depending downwardly a sufficient distance, as indicated at 141, for purposes which will presently appear. Said board 12 is preferably disposed substantially vertically and is also arranged practically transversely of the longitudinal axis of the boat. I have shown diagonally arranged braces 15, supportingly interposed between the gunwales and keel projection 10, but rigidly attached thereto so that these braces can act effectively both under tension and compression strains. I also relieve the points of connection between the ends of the board 12 and the gunwales, by providing a brace 16 which is interposed between the board 12 and the keel projection 10 and which is rigidly attached to the board 12 near the lower edge of the latter, as indicated at 17.

I have now described and shown an effective motor support and I wish it understood that even without the keel projection 10 and the braces 15 and 16, I could provide a strong and sufficient motor support, in some instances. However, I desire to still further strengthen and increase the efficiency of my improved support in such a manner as to perform a dual function, which I will now describe in detail.

One of the first weaknesses which a new row boat develops is the loosening of the connection of the oar look blocks, and that feature of my invention which I am now about to describe has to do with avoiding the block feature or defect and also strengthening my improved support. As illustrated, I provide blocks 9 which are formed integral with extensions 18 and these blocks 9, and the extensions 18 are shown rigidly secured to the inner and outer gunwales 3 and 4. Furthermore, said extensions 18 project rearwardly along the tops of the gunwales to the rear ends thereof and are suitably secured to the motor board support 12. Thus when the motor is not used, the rear oarlock blocks 9, which are most frequently used in rowing, are effectively reinforced against any tendency to loosen and the strain imposed on the blocks is not localized at their own points of attachment to the gunwales but is distributed along the extensions 18 in such manner as to protect and lengthen the life of the boat.

I have shown a typical form of boat motor which includes a casing 19, for the engine,

a crank wheel 20, a shaft sleeve 21 from which depends the propeller 22 and the steering vane or rudder 23. This motor, as usual, employs a steering bar or rudder handle 24 and is clamped in position by clamps 25 which preferably rest on top of and are secured to the motor board support 12, at the top edge of latter. Lower down, the motor is provided with an adjusting abutment 26 which engages the board 12 at a point near the lower edge of the latter and substantially abreast of the point of connection 17, of the brace 16.

It will now be clear that not only vibration of the motor, but also the propulsive thrust of the latter will be imposed wholly upon stern-wise projecting frame portions and that therefore the motor will operate without directly imposing any strain on the transom or planking. Thus not only the life of the boat is very greatly prolonged, but I prevent vibration of the motor from loosening junctures of the boat, thereby preventing leakage.

When the device of my invention is applied to double-ended boats, as shown more particularly in Figs. 1 to 6, I may mount both the forward and rearward oarlock blocks 27 and 28 on extensions 29 which latter are preferably integral with said blocks. The gunwales 30, either outside or inside, or both, may be extended from the point of stern convergence, as indicated at 31, and suitably mortised in the motor board support 32, as indicated at 33. The extensions 29 are shown extending in substantially parallel relation, as at 31, the ends being secured to the board 32 at 35. A similar keel projection, to that hereinbefore described, is indicated at 36 and diagonal and central braces are shown connecting said projection 36 with the extensions 31 and the board 32. The motor is not shown attached, in this form, but its application will be understood by reference to the preferred construction.

It is believed that the advantages and utility of my invention will be clearly understood from the foregoing description,

and while I have herein shown and described specific forms of my invention, I do not wish to be limited thereto except for such limitations as the claims may import.
